The 16C95x family includes multi-port variants like the OX16PCI954, which provides four UARTs on a single PCI interface. When using multi-port cards:
This decouples the driver from protocol handling, improving modularity. 16c95x serial port driver
// Disable THRE interrupt unsigned char ier = serial_in(port, UART_IER); serial_out(port, UART_IER, ier & ~UART_IER_THRI); The 16C95x family includes multi-port variants like the
: Software compatible with industry-standard 16C550 UARTs, ensuring it works with legacy serial peripherals. Implementation Details OS Compatibility ier & ~UART_IER_THRI)
The driver's FIFO trigger level configuration is the primary tool for tuning performance. The four sliders allow adjustment of:
